FILLINCREPLENISHING-LOOM BOBBIN CLEANER.

Application filed April 22, 1927. Serial Nix-185,725.

This invention relates to filling replenishing looms and more particularly to bobbin cleaning attachments applied to. such looms for removing the waste filling from filling carriers or bobbins as they'are successively ejected from the shuttle.

In that, type of filling replenishing loomsv wherein the bobbin is eject-ed from the shut.-

tle on replenishment and a fresh one inserted, an amount of waste fill1ng remains on the filling carrier or bobbin whlch must be removed before the filling carrier or bobbin can be rewound with filling. It is important, therefore, that the bobbin cleaning attachment shall be so contr1ved as to insure that all of the successive bobbins as they are ejected from the shuttle shall have the filling removed therefrom before they arepermitted to pass from the attachment. In attachments of this sort as heretofore constructed, the incoming filling carrier ejected from the shuttle is liable at times to be discharged from the cleaning attachment without being cleaned, a condition which necessitates hand manipulation ofvthe bobbins to separate the'clean'ed from the uncleaned bobbins and the removal of waste from the uncleaned' one's. An important feature of the present invention, therefore, consists in providing a filling replenishing loom with a bobbin cleaning attachment which will insure that each incoming filling carrier shall be cleaned of its waste yarn or filling before it is discharged from the cleaning attachment.

The inventionand novel features thereof and new combination of parts will best be made clear fromthe following description and the accompanying drawings of one good form thereof.

In the drawings: I Fig. 1 is a perspective view of the replenishing'side of the loom with some of the parts broken away, and having the present invention associated therewith;

Fig. 2 is a section through the bobbin cleaning attachment showing the bobbin in cleaning position; and

Fig. 3 is a similar section showing the cleaned bobbin as being discharged from the cleaning attachment and the .incoming bobbin as it is ejected from the shuttle.

In accordance with the present invention, a cleaning and an idle roll are normally held in close relation to'support upon them the filling carrier to be cleaned, and on replen ishment of filling the cleaned filling carrier is discharged by relative movement of the two rolls which are returned to their bobbin supporting positions before the completion of the filling replenishing operation.

In the drawings, the loom frame 1 is, or may be, of usual construction, and on the breast beam 2 is mounted the hopper stand 3 which is shown as having astud shaft '1 on which ismounted the rotary hopper 5 containing a series of filling carriers or bobbins 6 which are successively moved to replenishing position.

' Extending from the hopper stand is the stud or dead shaft 7 on which is mounted the transferrer 8 having an arm 9 connected with a dog 10 which, on call for replenishment of filling, is positioned to bestruck by a hunter on the lay to effect replenish: ment. This mechanism is, or may be, of usual type, and, being well understood in the art, requires no further description.

Secured to the loom frame is a bracket 11 having a rim portion 12 on which is supported the bobbin receiver 13 for receiving the ejected filling carriers or bobbins as they are delivered from the shuttle on replenishment of filling.

Extending transversely of the bobbin receiver 13 is a bobbin cleaner shaft 14.- on

which is mounted for rotary movement the bobbin cleaner 15 having a roughened surface which in the present instance is shown as a series of teeth 16. The shaft 14, Fi 1, is extended beyond the side of the bo bin receiver 13 and has a bearing 17 which may be appropriately supported by a bracket 18 secured to the loom frame. The shaft 14 is provided with a belt pulley 19 driven by a belt 20 from a going part of the loom,

such, for instance, as the cam shaft 21, on

which is mounted the belt pulley 22, the construction being such that' during the loom operation, the bobbin cleaner 15 will be rotated.

' Cooperating with the bobbin c1eaner'15 is an idle roll 23, and the cleaning roll and idle roll are normally in close relation or contact, it may be, to support a bobbin a, Fig. 2, between the two rolls, in bobbin cleanin position, so that the end of filling on the Imbbin may engage the teeth of the bobbin cleaner and be unwound from the bobbin.

- The two rolls and 23 are mounted formovement towards and from each other during replenishment of filling, for the purpose of discharging a cleaned bobbin between them, and immediately thereafter to return rolls before it is cleaned, and an important feature of the present invention therefore consists in means for separating the rolls for the discharge of the cleaned bobbin, and

immediately thereafter and prior to the completion of the replenishing operation, to cause said rolls to return to their initial bobbin cleaning position, so that the incomingfilling carrier to be cleaned will be caught by therolls and not be permitted to pass from the bobbin cleaner without being cleaned.

As shown in the present instance of the invention, the idle roll 23 is mounted upon a swinging arm 24 secured to the shaft 25 mounted in the bobbin receiver, and if desired a light spring 26 may be employed for normally holding the arm 24 with the idle roll 23 in close proximity to or in contact with the bobbin cleaner, 'as indicated in Fig. 2.

The shaft 25 has extending upwardly therefrom the arm 27 connected by a link 28 to an actuator 29. The actuator 29'is shown as pivotally .supported at 30. on the outside of the bobbin receiver and its downwardly extending arm is connected to the link 28 at 31. Extendinglaterally from the pivotal support 30 is the arm 32, the end portion of which has an inclined surface 33 which may be formed as shown by a hook member 34.

The transverse or change shaft 35 which, as usual, is mounted at the front of the loom for rocking movement in the bearings 36, has extending downwardl therefrom the arm 37, to the lower end portion of which is secured a carrier 38 for a one-way tripdevice. As shown in the present instance of the invention, the one-waytrip j device comprises a pivoted member 39, pivoted at 40 to the carrier 38, and has a trip or inclined surface 41adapted to engage the end of the arm 32' of the actuator, and

extending upwardly from the pivotal point.

40 the one-way trip has a stop member 42 which normally rests against a stop 43 when the parts are in normalposition, as indicated in Fig. 2, and durin the intervals between replenishment. of ling. The construction is such that on rocking movement of the transverse or change shaft and backward movement of the arm 37, the one-way trip device 39 will engage the end of the arm 32 and cause the actuator 29 to be moved u on its pivotal support 30 to separate the idle roll 23 from the cleaning roll 15 for the discharge of a cleaned bobbin, 7

and immediately thereafter the trip device 39 will pass beyond the end of the arm 32, thereby freeing the actuator, so that the cleaning and idle rolls are returned to their initial position before replenishment of filling is completed.

' Pivotally supported at 44 is the bobbin catcher 45, the lower end portion 46 of which is normally adjacent to the upper port on of the idle roll 23, and extending from the end 46 of the bobbin catcher is the arm 47. \Vhen the parts are in normal position during the weaving operation, they are as shown in Fig. 2, but when the idle roll 23 is separated from the cleaning roll 15, as hereinbefore described, the idle roll will engage the lower end of the bobbin catcher and move along the arm 47 which inclines from the main portion of the bobbin catcher,

mally supported in the position indicated in Fig. 2, but with permissive upward movement, by the idle roll.

When the ejected filling carrier is received into the bobbin receiver, the ejecting imioo ulse of the transferrer throws the incoming obbin with considerable force, and to arrest the bobbin under such conditions without injury thereto, the bobbin receiver has at its front portion a bobbin stop49 which may be preferably formed of canvas or other yielding material and supported at its u per end by a rod 50 and at its lower end y a rod 51 positioned preferably above the bobbin cleaner 15. i

From the construction described as one good practical form of the present invention, 7

it will be apparent that on call for replenishment of filling and rockin movement of the transverse or change sha t 25, the" one-way 'trip device39 will engage the end portion of the arm 32 of the actuator and swmg the actuator to move the idle roll 23 away from the bobbin cleaner, to permit the cleaned bobbin to pass between the two rolls, The

one-way trip 39 will continue its movement and trip past the end portion 34 of the arm 32, thereby freeing the actuator, and ermit the idle roll 23 to return to its initial obbin and prior to the completion of the fillingreplenishing operation, so that the incoming filling carrier cannot be dischar e'd from the bobbin cleaner until after it has n cleaned.

supporting position, as indicated in Fig. 2, 7

the cleaning roll to the rolls for cleaning purposes, and means On the return movement of the one-way trip gage the arm 47 of the bobbin catcher,

thereby lifting it into bobbin arresting'position so that the incoming bobbin may strike the stop 49 and then fall towards the bobbin catcher. The idle roll 23 having moved to its bobbin cleaning position, as indicated in Fig. 2, and prior to coming filling carrier, the bobbin catcher 45, which is inclined, will direct the incoming bobbin into bobbin cleaning position.

When the cleaned bobbn isdischarged from the cleaning position, as indicated in Fig. 3, it passes through the open bottom 52 of the bobbin receiver into the bobbin can 53 beneath, and when an accumulation of bobbins has been made in the bobbin can they may be taken to the winding machine.
